A constricting or compressing device used to control venous and arterial circulation to an extremity for a period of time.
Place the band at the back of the patient’s arm. A tourniquet should be placed 3 to 4 inches above the site of collection. Be sure to stretch it out enough. Make a loop with the tourniquet around their arm and cross the ends. Taking one end; loop it around the cross-section; and underneath. The loop and the natural compression of the cross-section will apply enough pressure to hold the band in place. Once the tourniquet is applied; make sure the patient is comfortable.
Never use a tourniquet for more than the recommended period of time.
It can be made up of latex or latex-free flat rubber.
